In Berber, tenseness is a phonological feature - not to be equated
with voicing or gemination - which can be added to all consonants
in any word position and context. This study investigates the perceptual
parameter(s) cueing tense consonants (/C*/) vs their non-tense counterparts
(/C/) in initial, medial and final position. We want to find out whether
tenseness is cued by VOT or closure duration for stops, and by the
duration or the intensity of the frication period for fricatives.
The test perception results show that, in the case of /t/ vs /t*/, the closure duration is the only cue that differentiates phonemically tense from non-tense consonant in medial and final position. But in initial position the information is involved in VOT combined with the following vowel intensity. For fricatives, the perceptual phonemic cue is the duration of the consonantal frication independently of its position and context.
